Asteroid Types

In Oxygen Not Included you have the ability to choose an asteroid type on which to found your colony. These are all variations on the same basic asteroid template intended to mix up early and midgame strategies. They all have different assortments of biomes, critters, and randomized traits.

World Seed
World seeds define the maps layout. They are completely randomly generated, but if you loved the map you just played on and just want to retry that seed, you can take that seed, enter it to the seed menu, then voila.

Version History
